A new polyacetylene glucoside (3E,5E,11E)-tridecatriene-7,9-diyne-1,2,13-triol-2-O-β-D-glucopyranoside (1), a new phenylpropanoid glucoside 2'-butoxyethylconiferin (2), and a new flavonoid glycoside 8,3',4'-trihydroxyflavone-7-O-(6''-O-p-coumaroyl)-β-D-glucopyranoside (3), have been isolated from Bidens frondosa together with fifty-three known compounds 4-56. The structures of these compounds w...
